The deflection and bending stress of a steel hollow beam of length 20 inches, width 30 inches, height 30 inches having a wall thickness of 10 inches and beam weight of 200 pounds can be calculated as follows : Inside width = Width - (2 * Wall Thickness) = 30 - (2 * 10) = 10 Inside Height = Height - (2 * Wall Thickness) = 30 - (2 * 10) =10 MI for hollow rectangle beams = (Width * Height3) - (Inside width * Inside Height3) / 12 =( (30 * 303) - (10 * 103) )/ 12 =66666.8106667662 Deflection = (Length3 * Force / (3 * Material * MI) * 0.0393701 = (203 * 200 / (3 * 30000000 *66666.8106667662)) * 0.0393701 = (1600000 / 6000000000000.03) * 0.0393701 =2.666660615337561e-7 inches Bending Stress = (Force * Length) / (MI / (0.5 * Height) = (200 * 20) / (66666.666666667 / (0.5 * 30) = 0.9 PSI
